When trying to create a new storage spaces pool in Windows 10 following error is displayed:
Can't create the pool
Check the drive connections and then try again
The request is not supported
The issue occurred because the PC had SATA Operation set to RAID (Intel Rapid Storage Technology) in BIOS. To resolve the issue I had to change SATA Operation mode AHCI.
Note: Changing SATA Operation Mode when Operating System is already installed can result in OS crashing with BSOD on boot. To prevent this read this post.
